[0002] After the production of steel plates is completed, the surface of the steel plates needs to be sprayed. At present, the spraying methods of steel plates include horizontal spraying and vertical spraying. Horizontal spraying requires reverse side treatment, has low spraying efficiency, and a large workload. Vertical spraying can directly spray both sides, which greatly improves the spraying efficiency. For example, patent application number CN202022440633.8 discloses a steel plate vertical spraying production line, including spraying equipment, steel plate clamping device, spraying room and dust removal equipment. Ventilation holes are provided on the top or wall of the spraying room, the steel plate clamping device is arranged on the top of the spraying room, the spraying equipment is arranged on one side of the steel plate to be sprayed, and the dust removal equipment includes a washing tower, an induced draft fan, a dust removal pipe, a dust removal hood and a cover net. The air inlet of the dust collector hood is connected to the spraying room and is arranged vertically below the steel plate to be sprayed, facing the steel plate to be sprayed, and the horizontal cross-sectional area of ​​the dust collector hood gradually shrinks from the opening to the dust collection duct to form an air outlet. The air outlet of the dust collector hood is connected with the air inlet of the washing tower through the dust collection duct. The hood net is made of rigid material and is covered on the air inlet of the dust collector hood. The bottom edge of the steel plate is located on the hood net, and the top edge is located in the steel plate clamping device and can move in the steel plate clamping device along the extension direction of the top edge.
